In python there are more than 40 inbuilt string methods, detailed explanation of some of the following
are given below.
inbuilt string methods in python 3.10
1. Split()- Being a competitive coder, this function is one of the most used function in my coding carrier.
This is a very simple and very important at the same time. This function helps in splitting a string with
help of a delimiter.
Ex:
s = "hello there"
s.split(' ')
output: ['hello', 'there']
2. format() – This is also a very important string function. It helps us to format any string. We give some
variables in {} and specify their value at the end of the string. It helps us in creation of dynamic strings.
Ex: txt1 = "My name is {fname}, I'm {age}".format(fname = "swapnil", age = 21)
Output: My name is swapnil, I'm 21
3. upper() and lower()– These two functions helps us to convert a string into uppercase or lowercase.
Str.upper() converts a string in uppercase and str.lower() converts the string into lowercase.
Ex:
s = 'Hi i am Swapnil'
print(s.upper())
print(s.lower())
output:
HI I AM SWAPNIL
hi i am swapnil
4. find()– This is also one of the most used functions and helps us to find if a sub string is present inside
a string or not.
This function returns starting index of the substring if the substring is present, else returns -1.
Ex:
s = 'Hi i am Swapnil'
print(s.find('Swapnil'))
print(s.find('hello'))
output:
8
-1
5. replace()– This function helps us to replace any substring of a string with any desired new string. It
takes old substring which is to be replaces and new string as its parameter.
Ex:
s = 'Hi i am Swapnil'
s.replace('Hi','hello')
output:
hello i am Swapnil
6. isalpha()– This function returns true if all the charecters in a given strings consist of alphabets,
otherwise returns false.
Ex:
s = 'apple'
print(s.isalpha())
s='1'
print(s.isalpha())
output:
True
False
7. isdigit()– This function returns true if all the charecters in a given strings consist of digits, otherwise
returns false.
Ex:
s = 'apple'
print(s.isalpha())
s='1'
print(s.isalpha())
output:
False
True
8. count()– This function returns count of any substring given as a parameter in this function.
Ex:
s = 'apple'
print(s.count('p'))
Output:
2
9. endswith() and startswith()– These functions checks if the string starts or ends with a substring
given as a parameter in these functions.
Ex:
s = 'apple'
print(s.startswith('a'))
print(s.endswith('e'))
Output:
True
True
10. strip()– This function helps in removing all the extra whitespaces from any string.
Ex:
s = ' apple '
s.strip(' ')
Output:
Apple
